Quit smoking symptom 6 weeks later?

Not sure if i am getting sick or not. Iv'e had the diarrhea for 4 days now and it seems to be getting worse, cramping and noises etc. I heard that this can happen when quitting smoking but i have not heard of it happening 6 weeks later? I know it can't be my ejuice because iv'e been vaping the same stuff, flavor and mg. I am wondering if it could be that my body is telling me that i am getting to much nic now and to lower it? I vape 12ml ejuice. I know you are not doctors but just wondering what you think?

Edit: forgot to mention i feel nauseated today too. Which is why i am thinking maybe i need to lower me nic?
